Subject: [PATCH v4 10/16] iommu/exynos: Clean up bus_set_iommu()
Date: Mon, 15 Aug 2022 17:20:11 +0100 [thread overview]
Message-ID: <d7477ef546479300217ca7bccb44da8b02715a07.1660572783.git.robin.murphy@arm.com> (raw)
In-Reply-To: <cover.1660572783.git.robin.murphy@arm.com>
Stop calling bus_set_iommu() since it's now unnecessary, and simplify
the init failure path accordingly.
